Application filed April 27, 1909. Serial No. 492,522.

ma c for instance of rubber, accordin to the general principles disclosed in my S Patents Nos. 743,636 and 812,648. I a;

found that in practice it is advisable and even necessary in some cases to shield certain portions of the ca from contact with the presser which won d otherwise deform. said portions or even tear them. For this purpose I have combined with the pressureexerting part of the apparatus a shield which covers and protects certain portions of the cap.

Reference is to be had to the accompanyin drawings in which *igure 1 is a sectional elevation showing one form of my apparatus in the act of applying :1 ca to a bottle; Fig. 2 illustrates a slightly di' erent construction before the application of pressure; Fig. 3 is a horizontal section on line 3-3 of Fig. 2 and Fig. 4 is a vertical section showing another form 01' presser.

T indicates a casing or holder provided -is left an annular chamber corresponding to the presscr ring G and in this annularchamher a sleeve R is movable up and down, said sleeve having slots for the passage of the bridge B. Tl. he sleeve can be moved by suitable mechanism not shown it being obvious that when the sleeve is moved toward the ledge T the presser Gr will be forced in ward as indicated in Fig. 1, as this is the only direction in which it may expand or yield. The cap E which made of sheet metal is placed on top of the bottle F, generally with the interposition of the packing ring or gasket 1). As clearly shown in Fig. 1 the block S conforms at its bottom to the shape of the top oi the finished cap and is provided with an annular peripheral shield S, which reaches down to the level below i that of the packing D. Thus when pressure is applied as indicated in Fig. 1 the presser G cannot reach the level of the gasket D or the top of the ca) and exert pressure or other stress upon the upper portion ofsaid cap and thus injury to this portion of the cap is avoided. It is of course understood that the block S bears on the cap with suiticicnt strength to hold the cap in position while the plunger or sleeve It moves down to press the lower peripheral or mantle portion of the cap into tight contact with the bottle neck. The pressure exerted by the rubber ring G is very great, hence the need of exposing to $1101 pressure only those parts of the cap which are to be forced against the bottle surface. If the presser G were allowcd to reach the portion engaged by the packing 1), there would be danger of serious injury to this part of the cap.

In the construction illustrated by Figs. 2 and 3 the apparatus has a slightly difl'ercnt formation for the lower end of the block S. This block is made with a chamber S to receive a raised portion E of the cap E, this cap being of the kind shown in my Patont No. 858,174. The block is provided with a shield S" surrmmding the chamber S and bearing on the he: of the cap adjacent to the projection 1Q. it will be soon that in this construction the upper wall of the chamber S does not come in contact with the cap, so that no pressure whatever is exerted on the projection E. The operation is otherwise the same as in the construction first described, and when compressed the prcsser G in this case takes a shape son'lewhat like that shown in Fig. at. If desired I may employ a prcsscr Cr having an internal ridge G to fit between the shield S and the cap E In some cases it is important that the block S should be adjusted accurately in relation to the prcsser, or in other words, to the ledge T on which the prcsser is seated. 'lhisis particdlarly the case when the cap has a formbl the character shown in Fig. 2.

In trier that the block may be adjusted readily, I may arrange its upper 'end to screw into thebriige 1B, the nut 0 serving to hold the block after adjustment;

I claim as my invention:

In an apparatus for a nlying caps to receptaeles, in which a yie in presser is em ployed, a block, against whic the rece tacle is pressed in the sealing operation, said 100k having a flangefor inclosing and protectin a portion of the cap from side pressure an being adapted to be raised or lowered 'so as v to bring the receptacle in the most efiective sealing position in relation to the resser.
